CARDUUS L., Sp. PI. 820. 1753. Thistle. 

 C. spinosissimus Walt., Fl. Car. 194. 1788. 



Dry pine-barrens along railroads near Fitzgerald, probably 



introduced. Fl. May. More common near the coast. 

 Widely distributed in the Eastern United States, mainly in 

 the coastal plain, but native range uncertain. 

 C. revolutus Small, Fl. 1307. 1903. 



Moist or intermediate pine-barrens, coffee, dooly, worth 

 (1607), colquitt. Fl. Aug. -Sept. Occurs also in the 

 Lower Oligocene region. 

 South Carolina to Florida, in the pine-barrens. 

 C. LeContei (T. & G.) Pollard, Bull. Torrey Club 24:157. 1897 

 Moist pine-barrens, coffee {1425). July, 1902. 

 Ranges westward to Louisiana in the pine-barrens. 

 SENECIOL.,Sp. PI. 866. 1753. 

 S. tomentosus Mx., Fl. 2:119. 1803. 



On rock outcrop in tattnall, April 26, 1904, in flower. 

 Said to range from New Jersey to Florida, Arkansas, and Texas, 

 but Dr. Mohr does not report it from Alabama, and its 

 distribution is not well worked out. Elsewhere in Georgia I 

 have seen it only on granite outcrops around Stone Moun- 

 tain, and in dry pine-barrens near Omaha. In the vicinity 

 of Dismal Swamp it is a common roadside weed, according 

 to Kearney. 



For a study of its leaf-anatomy see Kearney, Contr. U.S. Nat. Herb.

 supposed to be absent (see page in), in the northwestern

 farther inland, apparently under similar geological conditions, 

 in Houston, Early, and perhaps other counties.
